Thank you for visiting the Website for the Benton County Mosquito Control District. Since 1969 we have been providing mosquito control services. We hope that this website answers your questions and increases your knowledge of mosquitoes and mosquito control activities. If you can't find what you're looking for, please feel free to contact us.
The Benton County Mosquito Control District is dedicated to responsibly improving the quality of life and increasing public education in our area. The District accomplishes this by utilizing Integrated Pest Management (IPM) strategies. IPM is designed to utilize cost-effective control measures to reduce mosquito populations and the diseases they potentially carry, while being environmentally sensitive.
Communication and cooperation with property owners, residents and governmental agencies are critical components in the effort to reduce mosquito populations. Benton County MCD strives to be open and responsive to our community.

West Nile virus; 2016 Recap
West Nile virus (WNv) has been a reoccurring mosquito-borne illness in our District and in Eastern Washington. In 2016, Benton County Mosquito Control tested 376 mosquito samples. We had a total of 38 mosquito samples test positive for the virus. 3 people and 2 horses also tested positive for WNv and sadly, one person passed away as a result of the illness.
Statewide there were a total of 9 people, 27 horses, 2 birds and 95 mosquito samples. Please note, that the vast majority of the state does not perform testing on mosquito samples. Human and animal detection usually occurs after symptoms have been shown (passive surveillance).
The District will continue to conduct monitoring of mosquito populations for the presence of West Nile virus in the 2017 season, as this is the best early indicator available for the presence of West Nile virus. But one should never assume that just because the Mosquito Control District hasn't detected WNv that it means it cannot be present.
The District advises using precautions to limit exposure to mosquitoes that potentially could be infected.
- Repellent; your best defense against bites
- Evening & morning have higher mosquito activity
- Pour out standing water weekly
- Even one bite can cause illness
- Long-sleeve shirt & pants
